Sand mastic in Wigmore
A silicone bead around a sash window can look out of place and does not suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. Common call-outs are for modern sealant on a period surround and gaps where the frame meets the masonry, across timber door frames, period & listed homes and brick reveals.
Houses in smaller places like Wigmore can stand more in the open than those in a built-up town. That is hard on the mastic around frames and sills.
Whatever the size of the job, it’s backed by our 12-month guarantee in Wigmore and across Medway.

Sand mastic in Wigmore: local notes
Wigmore is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Rainham (Kent) station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. In the older streets around St Paul's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Managing a site like Park Wood Infant School? Then the mastic around its windows and doors needs looking after like any other building’s.

Work for landlords, hotels and businesses
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Have rotten timber repaired before new mastic goes in
- Do not paint over the new mastic
- Find out about consent before window work on a listed home
- Keep sills and gutters clear so water drains away
Don’t touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours per window, depending on the condition of the joints, and the area is left clean. Parking around Wigmore is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- For business premises, tell us about site rules or sign-in
- Mention if the joints have been sealed before
- Move anything stored near the joints

Wigmore: your questions answered
Can you help a landlord with a rental near Rainham (Kent) station?
Yes. We work for landlords and letting agents as well as householders. You can call 0345 464 0079 or email us with the details for a clear quote.
Is sand mastic in a coastal place like Wigmore any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you have insurance?
Yes. Full insurance covers our work, and we can confirm the details when we quote.
Can new sealant go over the old?
No. We remove every bit of old sealant first, so the new joint bonds to clean surfaces.
What is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and finished to sit neatly against the masonry.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected, and the area is left clean when we finish.
Do I need permission for sand mastic on a listed building?
Check with your local planning authority. They’ll tell you if consent is needed for work to your windows.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it does not work out, we can redo it.
Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Surface by surface

What else we do in Wigmore
Why deal with it now?
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. In an older home around Wigmore, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
What you get with us
- We leave the area clean and tidy
- An ARBOMaster approved applicator
- A 12-month guarantee on all work
- Quality sealants from Arbo and Everbuild
